Demographic routes to variability and regulation in bird populations
Sæther, Bernt-Erik; Grøtan, Vidar; Engen, Steinar; Coulson, Tim; Grant, Peter R.; Visser, Marcel E.; Brommer, Jon E.; Grant, B. Rosemary; Gustafsson, Lars; Hatchwell, Ben J.; Jerstad, Kurt; Karell, Patrik; Pietiäinen, Hannu; Roulin, Alexandre; Røstad, Ole Wiggo; Weimerskirch, Henri (Journal article; Peer reviewed, 2016)There is large interspecific variation in the magnitude of population fluctuations, even among closely related species. The factors generating this variation are not well understood, primarily because of the challenges ... -
Density-dependent selection and the maintenance of colour polymorphism in barn owls
Kvalnes, Thomas; Sæther, Bernt-Erik; Engen, Steinar; Roulin, Alexandre (Peer reviewed; Journal article, 2022)The capacity of natural selection to generate adaptive changes is (according to the fundamental theorem of natural selection) proportional to the additive genetic variance in fitness. In spite of its importance for development ... -
The effect of climate change on avian offspring production: A global meta-analysis
Halupka, Lucyna; Arlt, Debora; Tolvanen, Jere; Millon, Alexandre; Bize, Pierre; Adamík, Peter; Albert, Pascal; Arendt, Wayne J.; Artemyev, Alexander V.; Baglione, Vittorio; Bańbura, Jerzy; Bańbura, Mirosława; Barba, Emilio; Barrett, Robert; Becker, Peter H.; Belskii, Eugen; Bolton, Mark; Bowers, E Keith; Bried, Joël; Brouwer, Lyanne; Bukacińska, Monika; Bukaciński, Dariusz; Bulluck, Lesley; Carstens, Kate F.; Catry, Inês; Charter, Motti; Chernomorets, Anna; Covas, Rita; Czuchra, Monika; Dearborn, Donald C.; de Lope, Florentino; Di Giacomo, Adrián S; Dombrovski, Valery C.; Drummond, Hugh; Dunn, Michael J.; Eeva, Tapio; Emmerson, Louise M.; Espmark, Yngve; Fargallo, Juan A.; Gashkov, Sergey I.; Golubova, Elena Yu; Griesser, Michael; Harris, Michael P.; Hoover, Jeffrey P.; Jagiełło, Zuzanna; Karell, Patrik; Kloskowski, Janusz; Koenig, Walter D.; Kolunen, Heikki; Korczak-Abshire, Małgorzata; Korpimäki, Erkki; Krams, Indrikis; Krist, Miloš; Krüger, Sonja C.; Kuranov, Boris D.; Lambin, Xavier; Lombardo, Michael P.; Lyakhov, Andrey; Marzal, Alfonso; Møller, Anders P.; Neves, Verónica C; Nielsen, Jan Tøttrup; Numerov, Alexander; Orłowska, Beata; Oro, Daniel; Öst, Markus; Phillips, Richard A.; Pietiäinen, Hannu; Polo, Vicente; Porkert, Jiří; Potti, Jaime; Pöysä, Hannu; Printemps, Thierry; Prop, Jouke; Quillfeldt, Petra; Ramos, Jaime A.; Ravussin, Pierre-Alain; Rosenfield, Robert N.; Roulin, Alexandre; Rubenstein, Dustin R.; Samusenko, Irina E.; Saunders, Denis A.; Schaub, Michael; Senar, Juan C.; Sergio, Fabrizio; Solonen, Tapio; Solovyeva, Diana V.; Stępniewski, Janusz; Thompson, Paul M.; Tobolka, Marcin; Török, János; van de Pol, Martijn; Vernooij, Louis; Visser, Marcel E.; Westneat, David F.; Wheelwright, Nathaniel T.; Wiącek, Jarosław; Wiebe, Karen; Wood, Andrew G.; Wuczyński, Andrzej; Wysocki, Dariusz; Zárybnická, Markéta; Margalida, Antoni; Halupka, Konrad (Peer reviewed; Journal article, 2023)Climate change affects timing of reproduction in many bird species, but few studies have investigated its influence on annual reproductive output. Here, we assess changes in the annual production of young by female breeders ... -
On estimation and identifiability issues of sex-linked inheritance with a case study of pigmentation in Swiss barn owl (Tyto alba)
Larsen, Camilla Thorrud; Holand, Anna Marie; Jensen, Henrik; Steinsland, Ingelin; Roulin, Alexandre (Journal article; Peer reviewed, 2014)Genetic evaluation using animal models or pedigree-based models generally assume only autosomal inheritance. Bayesian animal models provide a flexible framework for genetic evaluation, and we show how the model readily can ... -
Quantitative genetic modeling and inference in the presence of nonignorable missing data
Steinsland, Ingelin; Larsen, Camilla Thorrud; Roulin, Alexandre; Jensen, Henrik (Journal article; Peer reviewed, 2014)Natural selection is typically exerted at some specific life stages. If natural selection takes place before a trait can be measured, using conventional models can cause wrong inference about population parameters. When ... -
Sex-linked inheritance, genetic correlations and sexual dimorphism in three melanin-based colour traits in the barn owl
Roulin, Alexandre; Jensen, Henrik (Journal article; Peer reviewed, 2015)Theory states that genes on the sex chromosomes have stronger effects on sexual dimorphism than genes on the autosomes. Although empirical data are not necessarily consistent with this theory, this situation may prevail ...
